Centaurea (Cornflower; Bachelor's Button; Basket Flower)
Centaurea is a genus of about 500 species in the family Asteraceae, native to the Old World.
Centaurea plants have erect and hairy stems, narrow, lance shaped leaves and flowers arranged in the flower heads on top of the flowering stem. The flowers contain disk florets, such as those in the yellow center of a daisy, and petal-like ray florets on the periphery of the flower head.
The genus name was derived from the Greek word “kentauros”, which means “centaur”. The name has its basis in Greek mythology. Chiron was a centaur known for his knowledge of medicine. He used the Centaurea flower to heal his wounds. Chiron is credited with teaching mankind about the medical secrets and healing power of herbs.
The name “Cornflower” is gven because the plant often grows in cornfields.
The common name “Bachelor’s Button” has several possible origins.
English girls wore them to show they were eligible to marry. It was thought that if a girl hid the flower under her apron, she could have the bachelor of her choice.
The flowers were also worn by young men in love when they liked someone and wanted to date them.
Some believe the common name was given because the bud resembles a kind of button that required no sewing.
The common names “Cornflower”, “Bachelor’s Button” and “Basket Flower” are used for the entire genus but most often refers to the species Centaurea cyanus.
Centaurea symbolizes hope, remembrance, devotion, delicacy, anticipation, unity, fertility and love.
It can also symbolize wealth, prosperity and future.
